GAS CONNECTION
Use the gas line connections only with CE certified components.
The heater is supplied complete with:
- a dual gas valve;
- a gas governor and filter.
Al components are fitted inside the burner housing. To complete
the installation, as required by current standards, the following
components must be fitted by the installer:
- Anti-vibration joint
- Gas valve
FURTHERMORE,
using a high capacity gas filter without
pressure stabiliser is mandatory, as the gas filter fitted as standard
upstream of the gas valve has a limited surface.
NOTE: For ease of maintenance, connect the heater by
means of a seal and swivel gasket.
Avoid using threaded connections directly on the gas connection.
Current legislation allow a maximum pressure inside the
rooms, or thermal station, of 40mbar; higher pressure must
be reduced upstream of the boiler room or the site where the
heater is installed.

Gas valve
During the installation, it is recommended to tighten
the external gas supply pipe nut without exceeding a
tightening torque of 150 Nm for Ø 3/4”.
IT is strictly prohibited to supply gas to the circuit with
pressures higher than 60 mbar. Such pressures could
cause the valve to break.

To be provided by the installer
Pressure reducer
↑
Max 60 mbar
If pressure is higher than 60 mbar, a pressure reducer
must be installed at a distance of at least 10 m and no
pressure stabiliser must be fitted between the pressure
reducer and the heater, but leaving the gas filter.
